Despite having a smaller clip, and overall less damage than the M-9 Tempest, it is one of the most accurate weapons in the game. 


The M-12 Locust has a 240 rounds, and 20 rounds per clip (before upgrades). Through player driven tests, It has been determined that it has a a base DPS of 136 damage per second. According to an official post on the Bioware forums. it does 1.25 extra damage to armor, shields, and barriers. This makes it an effective weapon in all missions during the game.
